Abstract: | Jensen, Altschuler &Bard (1957) have surveyed the respiratory enzymes ofTrichophyton mentagrophytes. Enzymes of the hexosediphosphate, hexosemonophosphate, and tricarboxylic acid pathways were found plus a group of miscellaneous enzymes. In view of the close morphological, immunological, and nutritional similarities ofT. mentagrophytes toTrichophyton rubrum, we felt that a study of the enzymology of the latter organism had potential value in forming a basis for the comparison of the two dermatophytes. Our results showed that cell-free extracts ofT. rubrum contain glucokinase, TPN-dependent glucose and fructose dehydrogenases and separate TPN- and DPN-linked glycerol dehydrogenases. These results are in accord with findings of other investigators. ATPase activity was minimal, and shikimic acid kinase, and shikimic and quinic acid dehydrohydrogenases were not detected. |
